|(b)  Milestone
shall within 45 days after the end of each calendar quarter pay Sellers the amount of purchase price
owing to them for the quarter. Such payment shall be accompanied by statements showing the basis
used in calculating the royalties for such period and for each product individually.
(c)  For
purposes of this section 4 Net Sales shall mean gross sales less returns, discounts and allowances.
Purchase price payments for any quarterly period shall be adjusted in subsequent quarters to take
into account returns and allowances occurring in these later periods. If by reason of (d) below payments
are payable for only a portion of a quarterly period, Sellers shall be entitled to a payment in the
amount they would have received if they were entitled to royalties for the full quarterly period
multiplied by a fraction in which the numerator shall be the number of days in which they are entitled
to royalties and the denominator shall be 90.

|
|



|(d)  Payments
shall be made hereunder only until the expiration of the last patent covering any portion of device
or devices which embody the Proprietary Rights; provided, however that if no patent has issued and
a Milestone Product incorporating the Proprietary Rights faces substantial competition from other
products using similar technology the payment hereunder shall be appropriately adjusted by Milestone
to eliminate the competitive disadvantage.
(e) In addition Milestone agrees that
if one or more patents issues with respect to any pending or future patent application relating to
the Proprietary Rights, Milestone will, as soon as practicably thereafter, issue to Sellers five
year options to purchase an aggregate of 8,333 shares of Milestone Common Stock at an exercise price
per share equal to the fair market value of a share on the date of grant.
(f) Sellers by signing this
agreement confirm that (i) they are each an accredited investor within the meaning of
Rule 215 of the Rules and Regulations under the Securities Act, and (ii) they have acquired the shares
to be issued hereunder for investment and acknowledge that the shares cannot be resold or otherwise
disposed of until they are registered under the Securities Act and any applicable state securities
laws or an exemption from registration is available. Further since the shares will not be registered
at the time of issuance, the certificates representing the shares delivered hereunder will bear the
following legend:

10.           Binding Effect. This Agreement shall be binding upon and inure to the benefit of each of the parties hereto and their
respective successors, assigns and/or legal representatives. In the event that the obligations under
this Technology Sale Agreement, do not, for any reaon, automatically survive a sale or transfer of
all or a significant part of Milestones business or assets to a third party (the Transferee),
Milestone shall cause the Transferee to assume all of Milestones obligations under this Technology
Sale Agreement, as amended from time to time. If the undertaking of these obligations, whether by
way of automatic survival or by way of assumptions, in their entirety or in part, is impossible,
impracticable or of significantly different economic impact on Sellers, Milestone shall use its best
efforts to cause the Transferee to provide the Sellers with alternatives that are essentially equivalent
in value to the existing obligations of Milestone under this Technology Sale Agreement.
11.           Headings. The descriptive headings used and inserted in this Agreement are for convenience only and shall not
be deemed to affect the meaning or construction of any provisions hereof.

|12.           Entire Agreement. This Agreement and any documents or agreements executed by the parties simultaneously herewith constitute
the entire understanding and agreement of the parties hereto with respect to the sale of the rights
described herein and supersede all other prior agreements or understandings, written or oral, between
the parties with respect thereto. This Agreement may not be amended except by a writing signed by
Milestone and the Sellers.
N WITNESS WHEREOF, the parties hereto have executed this Technology Sale Agreement as of the day and
year first above written.
